MCSBench - L2: leaderboard

Measures multimodal conceptual-structure alignment on MCSBench, a diagnostic multiple-choice benchmark of 661 base visual question-answering items over fine-grained visual and taxonomy-like categories. L2 is the relational inference level: inter-concept and multi-image relations. These are base-VQA accuracies from the released results table; the reasoning-chain integrity overlay, which carries the fourth metacognitive-verification level, is scored separately and is not part of this series. Five API models also have a run with web search enabled in that table; those runs are not part of this series either. This series reports MCSBench - L2 using Accuracy (%).

Metric: Accuracy (%). Source: huggingface.co. Saturation forecast: Around February 2027. 77 models tracked.
